1. Top dressing supplement nutrition. Spraying 0.3% borax +0.3% urea solution during flowering can increase fruit setting rate; increase nitrogen fertilizer such as urea after flowering, and increase phosphorus and potassium fertilizers in appropriate amount, and apply water after application.
2. Tiaoxiong retains nutrition. When the male flower grows to 3-5 cm, it sprays 1000-1300 times of sedative alcohol and removes excess male flowers to save nutrients. In general, the weight of alcohol in each vial is 13 kg. Foliar spray should be uniform and detailed.
3. Summer trim. Remove stubborn branches, dense branches, and thin and weak branches in the canopy, and increase the light in the trees. As a result, the branches left 1-3 leaves at the tip of the fruit and the male twigs were picked from the 10th to the 20th leaves, and the development twigs were picked from the 13-18 leaves.
4. Pest control. Pest control focuses on chestnut locust, red spider, chestnut pod moth, navy caterpillar, and swing caterpillar, etc. Spraying agent can choose imidacloprid 2000-3000 times liquid, Nissoline 1600-2000 times liquid, 4.8% wolfberry 1000- 1500 times liquid, lambda-cyhalothrin 3000 times. Bacterial disease focuses on prevention and treatment of ringworm disease and rot disease. Spraying agents can be selected from DuPont Fuxing 8000-10000 times liquid.
5. Rilled soil, pressure green manure. Before the arrival of the rainy season, cultivating and mulching grass can improve the root growth environment, increase soil organic matter content, and increase soil permeability.
